pable of in-band signaling prior to the call being answered. The option is in MMC
210. Under normal PRI progress control in-band signaling is provided after the call
is answered. This normal condition is set ON by default. To activate the feature and
provide in-band signaling prior to answer the setting should be changed to OFF.
ISDN SERVICE
PRIMARY RATE INTERFACE (PRI)
The iDCS 100 supports Primary Rate Interface ISDN. PRI allows simultaneous data
calls, calling party and calling line identification, high speed call setup and dis-
connect are among the benefits of ISDN calling. The 23+D configuration of ISDN
allows call information to be delivered via the data channel (the “D” of 23B+D)
thus leaving the bearer channels (the “B” of 23B+D) available for single use or
combined use to provide a wider bandwidth for data and video. The iDCS 100
supports the most popular protocol standards in the U.S.
PRI Protocols supported: National ISDN-2 (NI2)
AT&T No. 5 ESS
DMS 100/250
BASIC RATE INTERFACE (BRI)
The iDCS 100 BRI card supports trunk or station level Basic Rate Interface services
(BRI). Trunk or station BRI use is software programmable. BRI allows simultaneous
data calls, called party and calling number identification, high speed call setup
and disconnect are among the benefits of ISDN calling. The 2B+D configuration of
ISDN allows call information to be delivered via the data channel (the “D” of 2B+D)
thus leaving the bearer channels (the “B” of 2B+D) available for single use or
combined use to provide a wider bandwidth for data and video.
LAN INTERFACE (MEM4 CARD ONLY)
The iDCS 100 LAN card provides a 10/100 base T Ethernet interface for connection
to a data network. This interface allows a high speed connection for PC program-
ming across an IP network. This interface also allows the system software to be
uploaded to the Flash Memory via the PCMMC program.
LEAST COST ROUTING
Least Cost Routing (LCR) is the ability to automatically select the most cost effec-
tive central office route for the outside number dialed by any station. The iDCS 100
LCR program includes the following features:
z Option to use or not use LCR or a tenant basis
z Programmable LCR access code
z Digit analysis table 1000 entries each with ten digits for a iDCS 100 system.
z Routing by time of day and day of week (4 time bands per day)
z Routing according to individual station class
